1. add -w flag to print Entering and Leaving directory name the the beginning
and the end of processing.
2. export MAKELEVEL=$((MAKELEVEL + 1)) only in the child environment.
3. when printing error messages, prefix them with the program name [$MAKELEVEL]
for $MAKELEVEL > 0
4. if $MAKEFLAGS consists only of letters assume it is a set of flags (as
allowed by posix), convert them to -f -l -a -g -s, so that they get parsed
properly.
With those fixes gmake -> bmake -> gmake -> bmake etc. works as expected.
- Push /dev/random `information-theoretic' accounting into cprng(9).
- Use percpu(9) for the per-CPU CPRNGs.
- Use atomics with correct memory barriers for lazy CPRNG creation.
- Remove /dev/random file kmem grovelling from fstat(1).
rndsink(9):
- Simplify API.
- Simplify locking scheme.
- Add a man page.
- Avoid races in destruction.
- Avoid races in requesting entropy now and scheduling entropy later.
Periodic distribution of entropy to sinks reduces the need for the
last one, but this way we don't need to rely on periodic distribution
(e.g., in a future tickless NetBSD).
rndsinks_lock should probably eventually merge with the rndpool lock,
but we'll put that off for now.
cprng(9):
- Make struct cprng_strong opaque.
- Move rndpseudo.c parts that futz with cprng guts to subr_cprng.c.
- Fix kevent locking. (Is kevent locking documented anywhere?)
- Stub out rump cprng further until we can rumpify rndsink instead.
- Strip code to grovel through struct cprng_strong in fstat.
Parse_SetInput:
curFile->fname was using the buffer passed to it - which ReadMakefile frees.
This change makes the comment in ParseEOF about leaking curFile->fname true.
some shells; export MAKELEVEL like gmake(1) does.
2. It is absurd for the environment variable to be one greater than the
make variable!?!?! To wit...
printf 'all:\n\t@echo ${.MAKE.LEVEL}; printenv .MAKE.LEVEL' | make -f -
/usr/bin/clang-cpp. This allows rpcgen to work in a clang-only release
build. Document hack to be resolved when the final decision about
/usr/bin/cpp and friends is made.
